^^^^^^^^^^^^^^^^^
Don't use --getsize, this option is deprecated and it's based
on BLKGETSIZE ioctl that returns *32-bit* sector count (= 2TiB only).
Please, use --getsz. For more details see blockdev(8) man page.

patched to use --getsize64
That's wrong solution. The --getsize64 option returns size in bytes,
but you need size in 512-byte sectors. Use --getsz, read "man
blockdev" ;-)
